hacker!!!

hey,

I think I may have been hacked. I was having problems with my connectivity, so I started deleting programs that I never used. I think I deleted Adobe, windows messenger, Nero, a few things like that...when I got my connectivity back, my personal files were gone. It was like they were stolen, b/c there was nothing in the recycle bin in case I deleted them accidentally...

This came up on Norton:

I use a firewall and Norton Antivirus, so I don't know if files can be stolen or not...I know someone who had told me he could hack, but I don't know...how can I tell i've been hacked, and if it doesn't sound like i've been hacked, any clue where all my files disappeared to???? my folder which I had my files in are changed back to default for some reason too...I've learned a few things about IP addresses, pinging, and all that but I still couldn't find out anything solid. PLEASE HELPPPPPP
